H/.S ATTORNEY Patented Feb. 1, 1949 UNITED STATES PATENT o1=l=lct1v sorriso firmamos American Steel and WireA Company of New Jersey, a corporation of rsey Y Application July` 31, 1946, Serial N'. 687,268 (i Claims. (Cl. Zlio- 42) This invention relates to botting` apparatus for blast furnaces and the like.v

The present invention has among its objects the provision of an improved botting apparatus wherein warpage of the bott rod supportingl structure by heat from the furnace and molten cinder tapped therefrom is materially reduced. I

This and other objects of the invention will be more readily apparent in the following description of a preferred embodiment of apparatus within the teaching of the invention.

Botting apparatus heretofore employed has included a bott for stopping the opening in the furnace cinder notch, a bott supporting rod on the forward end of which the botttis attached,

and a structure supporting the bott and bott rod in line with the cinder notch and selectively ad@ vacing.. the bott into the cinder notch to stop the flow of cinder and retracting the bott to open the notch for the ow of cinder from the furnace. Typical of such prior apparatus is` that shown and described in my Patent No. 1,841,202, issued January 12, 1932, on which the apparatus of the preferred embodiment of the wpresent linvention is an improvement. It is to be understood, however, that in its broader aspects some variations are possible and that the present invention is not limited to the structure of the preferred embodiment.V

Prior to the present invention, which provides a liquid-cooled bott rod supporting mechanism, such structure required considerable maintenance to keep it in good operating condition.v

The means for supporting the bott rod and for allowing its reciprocation toward and from the furnace, generally termed the botting rigging, is

'coming' unduly heated. Such result is accomsubjected to very high temperaturesbecause of its location in the immediate vicinity of the -fu'rnace and its cinder notch, and, in at leasta portion of its travel, substantially above the cinder runner. The heat emitted from the furnace,

the cinder notch, and the molten slag or cinder passing beneath the rigging caused warping to occur in prior botting rigging structuresboth in the framework carrying the bott rod and the supporting beams therefor. Such warpage ob` viously causes poor operation of the betting'v ap paratus in that the bott rod is thrown out of alignment with the cinder notch opening in the furnace and the traveling frame tends to bind on the. supporting beam or beams, `due towarpageof both the frame and the beam or beams.

The apparatus of the presentV invention over I comes the above ldescribed 'dimculties arising?k from distortion ofthe betting rigging by its plished, as above indicated, by the provision of liquid cooling means for the bott rod -support and for the means for allowing movement of the rod' to and from the cinder notch.

The invention will be more readily understood byreference tothe accompanying drawings, in which:

`Figure 1 is a view in side elevation of a preferred embodiment of the improved betting apparatus, lthe furnace in the vicinity of the cinder` notch being shown in section;

Figure 2V is an enlarged View in side elevation of the botting apparatus shown in Figure 1;

Figure 3` is a view in plan of the bottin'g apparatus and its attendant mechanism; and

Figure 4 is a view in vertical section of the supporting beam, the section being taken alongl to the flow of cinder therethrough, except when the cinder is tobe tapped, by bott IU, shown in Figures 1 and 2A in retracted position. The fura nace is` provided with columns 1, which aid in supporting the furnace Walls and to which various furnace appurtenances, such as the blast pipes leading "to the tuyres and the forward end of the bott supporting and reciprocating structure,Y are affixed.

The betting apparatus shown is generally similar to that disclosed ih Patent No. 1,841,202, above referredrto, in that it has a horizontal member I5, of generally I beam cross section, positioned above the cinder notch and in a vertical plane containing the'axis of the cinder notch opening. Member I5, which provides a trackway upon which the bott rod supporting frame travels, is supported at its forward end by rea'- `-`son of its attachment to the transverse hollow member 5, 'which in turn rests upon brackets Gattached to columns 1. Member 5 may be' attached to beam` f5 as by shackles I6 embracing rodfl'lazbelng .joinedto the bott rod supporting being provided with the memberf 30',

Such frame is arranged to be supported from beam I5, and to travel therealong, by sets of opposed rollers 22 in suitablewhanger members attached to the top of the frame. the top surface The bott rod supporting frame may be selectively advanced toward and retracted from the* furnace by various known means, of which Athat y employed in the botting apparatus disclosed in Patent No. 1,841,202 is one.

runs extending lengthwise of beam I 5,' member 30' being supported by the vertical idle'pulley;`

40 adjacent the forward end of beam I5 and the horizontal idle pulley system 32 of beam I5. From such latter pulley system member 30 'passes to winding mechanism indi-f Figure 3. The windingcatedv generally at 42 -in mechanism is so constructed as to cause opposed runs of'member 30 to `travel in opposite directions lengthwise of beam I5, so that by attaching thebottrod supporting frame to one runv of hanger forrolls 22 to the lower run of member rotation of the winding mechaproachv the furnace and rotation of the vwinding mechanism in the opposite direction causes the frameto be Vretracted from the furnace. -The winding mechanism may, if desired, be provided` with a-counterweight device (not shown), such as disclosed in Patent No. 1,841,202, for causing f- `the,-bott rodsupporting frame to travel toward the furnace.

The beam I5, in accordance with the present invention-is of hollow construction to allow 'it tobe'cooled by liquid circulating through it underpressure. A preferred manner `of making beam composed of parallel side the side pieces being The space-enclosed with- I5, .the outlet pipe 9 from member 5 being con-fr nected to the forward end of the coolant space withinbeam I5.V The supporting memberv 5, as wellpas beam I5, is thus liquid cooled.

Thebott rod supporting frameor trolley is alsof; cooled by liquid coolant flowing therethrough. Such frame, which is of ,generally Arectangular shape, consists of atop pipe member i II,-.gaiparallel bottom pipe member, I8, front and rear vertical pipe members 20 and I9, respectively, and a diagonal bracing pipe member 2l. Alliv such pipe members are connected to reach other :as fshown, .preferably by Welding, so as to have intercommunicating passages therethrough. Coolant` liquid for the bott I and bott rod I2 is led thereto throughfpipe Il, which connects with aninternal pipe I4 which extends through bottom frame member I8 and bottrod or pipe I2 to a point: adjacent the forwardiend of the .hollow Rollers 22 engage' and-'r'ideupon f of the bottom flange of beam I5;y

Such i mechanism comprises a exible member`30 having'opposed such as by connecting the rear I5 is shown in Figure 4 wherein itis shown pieces I6.` and I6', y

I6', and I6'` constitutes.a':llquid pipe 8- andfrcm which the liquid-i by flexible hose 34.'l which: is of sulicientflength to allow full travelof the frame between its forward and rear limits, travels through pipe I4 'fun'til it is discharged from such pipe with bott I,ll.l Thereupon such liquid travels back toward andinto the frame in the space between pipe rod orf-pipe I2 and bottom frame member I8. Thence the coolant travels upwardly,` vin the directions indicated by the arrows in Figure 2, through members I9, 2U, and 2| into 'member II. Pipe at the rear end 36, connected to the rear end of member I'I, to which exible hose 38 is connected, provides for the discharge of the heated coolant to a'suitable-sump.-v Y

The apparatus described hasl the advantage that thelpipe'lengths Il through 2| together constitute aureservoir Tof coolant liquid of substantial vcapacity which Vconstantly maintains a static vhead`ofpressure on thecoolant in the rod I2, thus insuring more effective cooling thereof.` Continued cooling is provided, furthermore,r even should thesupplyfofgliquid to connection34 be` interrupted tempora'rily.- "This minimizes the likelihood that the bott-,IU will be overheated and damagedw- .Because f'of its cheapness andsavailability'at a furnace such asa blastfurnace, whereit is'employedi-ffor cooling the tuyres. and various parts of .the cinder notch,.water. makes an ideal liquid coolant 'for' Y the..4 liquid -cooled .members of the botting lapparatus of zthe, present invention; Such" water' may be introduced 'into the coolant receiving `spaces vof the .apparatus at the pressuresfemployed for the tuyre: and -cinder notch coolant Water.. g n i; Havingl thus. fully.Y described ai4 preferred: embodiment'of .the improved botting apparatus Yof the` rpresent invention, vIv desire f? to `claim -as' new thefollowing:..a I, J
